GCA-Washburn Tunnel

Year Submitted: 2003

Process: Wastewater Treatment

Industry: POTW

Wastes Reduced: Wastewater

Substance: Organics

Equipment: Piping

Location: Pasadena TX

No. of employees: 35

Contact: George Meriwether

Phone: (713) 472-5507



Description:

The Gulf Coast Authority is a publicly owned waste treatment authority that operates several treatment facilities in the Houston area. The Washburn tunnel facility recently constructed a new belt press station to dewater sludge. The new facility reuses effluent water for belt press process wash, foam control, primary sludge flow control and general plant wash down. Reuse of this water significantly reduces the fresh water requirements of the facility.

Environmental Benefits:

Approximately 530 g.p.m. of plant effluent is used for the belt press with the plant using approximately 800,000 gallons/day.

Details of Reductions

Additional Information :

If this water supply had to be purchased at the rate of $0.0021/gallon, the additional costs to GCA would have bee $613,000 per year. The pumps and associated piping to distribute reuse water plant wide were a small fraction of this amount.
